The House of Representatives passed the controversial bill to revise the 1947 education law Thursday amid an opposition camp boycott.
The passage brings Prime Minister Shinzo Abe one step closer to achieving his goal of getting schools to instill a sense of newly defined patriotism in their students.
The Democratic Party of Japan, Japanese Communist Party, Social Democratic Party of Japan and People's New Party had demanded more time for deliberations on the bill by a Lower House committee, and thus began their boycott Wednesday when the panel voted on the bill.
